About formats

MTS is a file extension associated with the AVCHD recording format, jointly developed by Sony and Panasonic for high-definition consumer camcorders. Files with the MTS extension contain MPEG-2 transport stream data carrying H.264/AVC video at resolutions up to 1920x1080, paired with Dolby Digital (AC-3) or LPCM audio. The MTS designation is used when AVCHD content is accessed directly from the recording media, as opposed to M2TS files which typically refer to the same transport stream format in Blu-ray disc contexts. Consumer and semi-professional camcorders from Sony, Panasonic, Canon, and other manufacturers write MTS files into a structured directory hierarchy on memory cards or internal storage, accompanied by index and playlist files that organize clips for in-camera playback. The transport stream packaging includes timing information critical for maintaining audio-video synchronization and supports features like random access points for efficient seeking. MTS recordings preserve the full quality captured by the camera sensor, making them suitable as source material for editing workflows. The use of H.264 compression provides an effective balance between video quality and file size, enabling extended recording times on commonly available SD and SDHC memory cards. MTS files are recognized by all major video editing applications and can be imported directly into editing timelines, though some workflows benefit from transcoding to editing-optimized formats for smoother real-time performance.
Developer: Sony & Panasonic
Initial release: June 2006
GSM 06.10 (Full Rate) is the foundational speech codec of the Global System for Mobile Communications standard, ratified by ETSI in 1991 and deployed across hundreds of cellular networks worldwide. Operating at a fixed 13 kbit/s, the algorithm applies Regular Pulse Excitation with Long-Term Prediction (RPE-LTP) to compress 20 ms frames of 8 kHz mono speech into just 33 bytes each. This approach models the vocal tract as a linear predictive filter, encodes the excitation signal, and leverages pitch periodicity for further reduction — tuned to deliver intelligible voice under the bandwidth constraints of early digital mobile channels. The codec powers not only GSM telephony but also many VoIP applications, voicemail systems, and IVR platforms that benefit from its low bitrate. Three concrete advantages stand out. First, extraordinary compression: one minute of speech fits in roughly 100 KB, enabling efficient storage and transmission. Second, universal tooling — libraries such as libgsm and SoX handle encoding and decoding on every major platform. Third, a royalty-free patent landscape that has encouraged adoption across open-source telephony projects like Asterisk and FreeSWITCH.

Frequently Asked Questions

Why convert MTS to GSM?

GSM provides GSM 06.10 speech codec for cellular telephony. Converting extracts compatible audio from your MTS camcorder recordings.

What software handles GSM?

Specialized audio tools, SoX, and format-specific applications handle GSM files for playback and processing.

Is GSM widely supported?

GSM serves specific use cases. For general audio needs, MP3, WAV, or FLAC are more broadly compatible.

Can I adjust encoding settings?

Yes — configure sample rate and encoding parameters before converting to match your target system requirements.

Is batch conversion available?

Upload multiple MTS files and extract GSM audio from each simultaneously in one session.
